"Ou te bien enjoy?"
Here's a breakdown:
* Ou: You
* te: Did (past tense)
* bien: well, really
* enjoy: have fun
You could also use:
* "Ou te jwi?" (You did enjoy?)
* "Ou te pase bon tan?" (You passed good time?)
The choice depends on the specific dialect of Creole and the level of formality you want to convey.
